Doesn't the process of "commiting" take time?

I don't really understand how disabling Autocommit prevents problems from occurring as a result of unintended interruption. Doesn't the process of writing to disk take time so it's still possible that an interruption can corrupt the process of writing to disk?

The kind of "interruption" mentioned here is probably between statement entries.

In the case of commit, all the statements have been entered, so an interruption of the statement entry sequence (or the client-server connection) would not affect the completion of the process, even it it requires a bit of I/O time.
